after abs light, trac warning message, radio goes out and message center wont restart

[lsgranny]

I have read many posts on here about rear wheel speed sensor causing traction light but will that also cause radio and message center to black out....then car shuts off?? I can only restart it if I unhook the battery....and with a jump. I am wondering if a problem is somewhere other than the rear wheel speed sensors? Please help...!?? can a bad alternator cause loss of power...which then sets off the abs light &tract warning??

Put a new battery in it, make sure it's OEM and double check the terminal connections and ground.
The LS does funky things all over when the battery is near done. If you are lucky you won't need a new alternator.
